Title: Network communication system
Inventor: POON TOMMY C
IPC: H04J11/00
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To attain re-configuration for a demodulator and a modulator without increasing the number of demodulators and modulators by detecting a channel parameter and changing a modulation format of sent information according to the detection. SOLUTION: A header is always QPSK-modulated and sent repetitively periodically during transmission of a data signal. A receiver configures itself to the QPSK demodulation mode just after application of power supply, and after detecting a header word exquisitely, the receiver reconfigures itself. After detection of a prescribed noise level, a different modulator type is selected to enhance the reliability of communication. When two devices both using a conventional MODEM come the traffic, a modulator type is switched over depending on detection of any degradation in the communication state. This is conducted by using a channel noise detector 258 connecting with a controller 208 detecting a noise on a channel. Then, the controller 208 designates a proper modulation format, a proper frequency and a proper band width to realize communication with higher reliability.

IPC: E03D11/16
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To improve workability by forming a flange main body in a thin disk shape without arranging a sanitary earthenware installing bolt installing part, and forming an installing bolt as a separate member. SOLUTION: A cylindrical socket outer cylinder 2a composed of rubber having lips 5, 6 having an outside diameter brought into close contact with an inside diameter of a connecting waste pipe 16 and having a difference in a diameter, is fitted to the outer periphery of a cylindrical socket 1 having a thin plate disk-shaped flange on the upper end to constitute a sanitary earthenware installing socket flange. The connection of a waste port 20 and the pipe 16 of a sanitary earthenware works well when fitting an outer cylinder 2a of the socket flange to an inside diameter of the pipe 16, and the lips 5, 6 make a seal by being deformed according to the size of the inside diameter of the pipe 16. Next, the sanitary earthenware is fixed by a bolt of a separate member preerected outside the thin plate disk-shaped flange.  Thus, since a bolt position is not fixed, a sanitary earthenware installing flange can be commonly used for plural kinds of sanitary earthenware, and can be commonly used for a waste pipe having a different inside diameter, and since the bolt is not held by the flange, the flange can be formed as a thin plate, a diameter is reduced, and a cost can be reduced.

IPC: H04L12/70
Filed: 1990-12-18
Abstract: PURPOSE:To prevent the collision of the retransmitted packets and to improve the packet communication efficiency by giving the priority to the packet that is sent again to a switchboard or a terminal for the start of retransmission if the packest collide with each other. CONSTITUTION:When the packets are simultaneously sent from a terminal 10 and a switchboard 20, a packet collision detecting part 24 of the switchboard 20 detects the collision of packets and reports this collision to a packet collision communication signal transmitting part 25. Thus the part 25 informs a packet collision communication signal receiving part 14 of the terminal 10 and a packet transmitting part 21 of the switchboard 20 of the occurrence of the packet collision in order to stop the transmission of packets against the switchboard 20. The part 14 receives the information of the packet collision and instructs a packet sending part 11 to continuously stop the transmission of packets despite the time-out state of a packet sending interval timer 13. The part 21 starts the transmission of the collided packets when a packet sensing interval timer 23 is set in a time-out state.
